A Gentle Intro to TypeScript
TypeScript enhances JavaScript by adding type annotations that catch errors during compilation, making code more robust and easier to read. Switching to TypeScript involves adding type annotations to your functions, which the TypeScript compiler uses to infer types and ensure only valid operations. This can prevent entire categories of bugs frequently encountered in JavaScript. Tools like Deno and Vite simplify TypeScript adoption by automatically handling TypeScript to JavaScript compilation.

Self-contained Executable Programs with Deno Compile
Deno compile allows developers to turn JavaScript and TypeScript programs into self-contained, cross-platform binaries, eliminating the need for a runtime or dependencies. Deno 2 has introduced improvements such as support for npm packages, smaller binary sizes, and code signing. The process simplifies deployment, improves startup times, and offers enhanced security through preserveable permission flags. Examples include creating a single executable, cross-compiling for different OS, code signing, and even compiling npm packages for performance boosts.

How to convert CommonJS to ESM
ECMAScript modules (ESM) are the modern standard for writing JavaScript, supporting features like async loading and better compatibility. This post guides you through updating the syntax of a legacy CommonJS project to ESM, including changes in import/export statements and package.json configurations. Removing 'use strict' and using shims for globals like __dirname and __filename are also discussed. Tools like VSCode and various npm packages can assist in the transition. Adopting ESM can alleviate compatibility issues and streamline development.
